About Parish's Nightshade (Solanum parishii) Parish's Nightshade (Solanum parishii) is a native shrub in the Solanaceae (Nightshade) family that grows in primarily in two disjunct regions, the mountains and valleys of northern California and the chaparral of southernmost California. It occurs from sea level up to elevations of 6,000 feet. A closely related species is Solanum xanti, and their ranges overlap in the southern counties. There are also several non-native species of Solanum that look very similar. Some are sold under the common name Potato Plant. The flowers of Solanum parishii are small but attractive. As with many other members of this family, the plant is poisonous to humans and some other animals, especially the fruits. Be cautious in using it where children or pets may have access. Due to the poisonous nature of many nightshades, tomatoes (also a member of the Solanaceae) were thought to be equally toxic by many North Americans as late as the early eighteenth century.
